JACOB A. ROSER, OF LE GORE, MARYLAND.

FODDER-MACHINE.

To all whom 'it may concern:

Be it known that I, JAoon A. Rosnn, a citizen of the United States, residing at Le Gore, in the county of Frederick, State of Maryland, have invented certain new and useful Improvements in Fodder-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to fodder machines and particularly to cutting devices included therein.

The object of the invention is to provide a novel construction of cutting mechanism for fodder machines which will split and cut up fodder in the form of exceedingly fine flakes.

WVith these and other objects in view, the invention consists in certain novel features of construction as hereafter shown and described and then specifically pointed out and claimed, and in the drawings illustrative of the preferred embodiment of the invention. 1

In describing the invention in detail, reference will be had to the accompanying drawings, wherein like characters of refer? ence denote corresponding parts in the sev-. eral views; and in which- Figure 1 is a side elevation of the end of a fodder machine which carries the cutting. mechanism, the view being partly in section the better to show the operating parts of the cutting mechanism therein. Fig. 2, a top plan view of what is shown in Fig. 1 with the top of the casing removed to show the operating parts. Fig. 3, a side elevation. from the side opposite to Fig. 1 showing the casing and gearing on the outside thereof. Fig. 4, a detail View of the slitting and platen rolls, and Fig. 5 is a cross section through Fig. 4 showing the same parts to-- gether with the cutting knife and a portion of the cutting cylinder.

Referring to the drawings the numeral 10 indicates the general frame work of the machine and this frame work is supported at the end shown on a suitable wheeled axle 11. The frame work 10 is surrounded by a casing 13 in the usual and well known manner.

The casing is cut away at the forward end to provide a feeding opening 16 and access is had to this opening by means of a stand- Specification of Letters Patent.

ing board 17 supported adjacent the opening by suitable chains 18.

Immediately below the opening 16 is a feeding platform 19 provided with a sheet iron cover 20. This platform extends rearward from the front end of the machine and at the rear end of the platform are provided crushing rolls 21 which are supported on shafts 22 and 28, the shaft 22 being the lower shaft and supported in fixed boxings 24 attached to the side frames of the machine while the shaft 23 is the upper shaft. The shaft 23 is mounted in boxes 25 which are slidable vertically between guides .36, the boxes being provided with suitable lips to engage over the guides for this purpose. These boxes are normally held in their lowermost position, this being the position in which the two rolls 21 will be pressed firmly against each other, by means of heavy steel coil springs 27 one end of each of which is seated on one of the boxes 25 while the other end bears against a spring seat 28 supported in the frame work. Each of the rolls 21 has a surface which is in general contour truly cylindrical but is provided with fine grooves 29 which extend lengthwise of the cylinder for the purpose of drawing in the fodder. The springs 27 are of sufficient strength to normally maintain a layer of crushed fodder about 1- inch thick between the rolls and the movement of the upper roll is preferably about 1:}- inches which allows for extra heavy feed passing through the rolls while at the same time insuring against the breakage of the rolls by any extraneous substance passing therethrough. It has been found by experiment that the springs 27 should be suiticiently strong to give a pressure of about ten tons to the upper roll to insure the maximum elliciency of crushing corn fodder.

Immediately to the rear of the rolls 21 is a table 30 similarly constructed to the table 19 and to the rear of the said table 30 are the slitting rolls. The upper slitting or splitting roll is indicated by the numeral 31 and this roll is carried on a shaft 32 which runs in suital'ile boxes 33 provided with springs 34 and arranged similarly to the boxes 25 of the crushing rolls with the exception that the springs 34: are light springs for the purpose of maintaining a slight pressure between the slitting roll and its platen. This slitting roll consists of alternate circular knives 35 and washers 36 which are secured movement of the slitting roll is limited by a stop 41 at each'end of the shaft.

To the rear of the slitting rolls is a third table 42 similar to the other two tables and provided on its under side with a bar 18 Whereto is bolted a shear blade 4 1.

At 15, is a shaft whereon is supported a cutting cylinder 46 provided with a plurality of spirally arranged pockets 17 in each of which is mounted a shear blade 18 adapted to work against the shear blade dd as the cutting cylinder isrevolved. Adjusting bolts 419 pass through the rear of these pockets and engage the blades 48 so that by turning these bolts the blades may be properly adjusted to bring their edges against the shear blade 1%. These bolts 19 are held from movement longitudinally of the pockets by means of bolts 50 the ends of which extend into grooves 51 cut around the bolts and the bolts 49 are further locked in position by means of suitable lock belts or set screws 52. By means of this construction the blades 48 can be adjusted to a nicety so that their edges will at all times lie in proper relation to the shear blade 14:.

It is to be noted that the slitting rolls have a slightly greater peripheral speed than the crushing rolls so that the layer of fodder passing through the latter is slightly drawn out and it is also to be noted that the cutting cylinder is preferably ar ranged so that the split fodder is cut into pieces about of an inch long. It will be obvious, however, that this latter size may be varied by varying the speed of the cutting rolls or the number of blades thereon.

In order to properly tension the springs for the slitting and crushing rolls the springs for these rolls are provided with adjusting screws 102.

In order to drive the cutting mechanism the shaft 15 of the cutting roll is provided on its end with a projection which extends through the casing 12 and has mounted thereon a belt pulley 103 which is connected by means of a suitable belt 104 to any desired source of power. The shaft 415 is provided with a belt pulley 107 which is connected by means of a belt 108 to a pulley 109 mounted on a shaft 96. This shaft 96 extends through the frame work on the is mounted on the shaft 10 and is engaged by the chain 111 and a sprocket 117 is mounted on the shaft 22 and is engaged. by the chain 114; By means of this arrangement the crushing and slitting rolls are operated as will be observed.

It is obvious that minor changes may be made in the form and construction of this invention without departing from the material principles thereof. It is not therefore desired to confine the invention to the exact form herein shown and described, but it is wished to include all such as properly come within the scope of the appended claim.

Having thus described the invention, what is claimed as new, is

In a fodder preparing mechanism, a feed ing table, crushing rolls in the rear of and supplied from said feeding table, an lntermediate table at the rear of said crushing rolls, slitting rolls comprising a platen roll and a roll having circular knives spaced therealong to the rear of said intermediate table, said slitting rolls being arranged to form a continuous cut through the material passing from the crushing rolls, a cutting table having a knife at its rear edge to the rear of said slitting rolls, a cutting cylinder Copies of this patent may be obtained for five cents each, by addressing the Commissioner of latents.
